VEVEY, Switzerland: Root canal preparation is an essential step in endodontic treatment and aimed at removing the current content of the root canal and preparing it for filling. The objective is to prevent the onset or recurrence of apical periodontitis. The use of rotary instruments with continuous rotation has made treatments faster, more comfortable and more predictable over the past 20 years. Many developments in instrumentation have helped improve preparation systems. But despite all these advances, the complexity of root canal systems results in unprepared or unpreparable areas that require the complementary use of chemicals for cleaning.
VEVEY, Switzerland: A new generation of irrigation needle designed and manufactured by Swiss endodontic company PD (Produits Dentaires) enables more effective cleaning and disinfection in root canal therapy owing to its unique flexibility and exceptional irrigation capabilities.
The development of a new product requires drive, curiosity and the ability to be open-minded in order to dig deeper and to pursue the information necessary to bring the product to life. The process can take several years, depending on its complexity, and the flexibility and responsiveness of the team involved make all the difference—like in the case of EssenSeal, a new-generation zinc oxide eugenol sealer featuring tea-tree essential oil launched by Produits Dentaires (PD) in 2019. In this interview, David Brendlen, the biomaterials engineer in charge of the R & D team, and Baptiste Reuse, R & D project manager at Produits Dentaires, explain the research, development and production process they followed for EssenSeal.
